Climate change impacts in river India: floods, soil erosion and adaptation policy.
States like India should make the control of flood and riverine erosion the core of a national adaptation drive in aftermath of devastated years. Together, climate adaptation and riverine states have asked to use of both natural method with artificial engineering, where in more acknowledgement of erosion along with flood would exist as a disaster policy; it means that at the policy level, erosion alongside floods will now appear as disaster which need immediate solution.
The crisis on the ground over a million people were left without homes/ shelter and 99 people died during month Of june and August due to flooding and soil erosion during floods, especially in northeastern India; Assam’s disaster-management agency recorded this damage only for river systems of Barak and Brahmaputra, the largest Indian rivers. 487 million dollars and 182 million more dollars from Asian development bank for flood control, river-bank protection the Brahmaputra river, were made available in February, in second phase for which flood-and river erosion-control in the Brahmaputra had its second round of funding. This amount of 162 million dollar will support climate-change adaptation project. According to a study, increasing levels of natural risk are now driven not only by climate change, such as increases in rain/ glaciation, but especially by man-created activity which consist of; un managed urbanisation; wetlands covered over due to the influx of silt, concrete barriers are thus put which stops natural drainage channels which follows river ways; as well as future more intense floods. This would enhance the destruction of natural land and wetland systems in Assam’s river-affected area in long term, and even more for areas like; Ganga, Brahmaputra river areas due to it proximity river banks.
Policy response and climate adaptation funding the country has received a second round of funding to tackle floods in Brahmaputra valley in January, including adaptation finance, although more support still remains important for adapting river systems from India ‘s impact; flood- and riverbank erosion-control measures taken till now include over half-a-billion dollars being allocated to combat flooding of the Brahmaputra. As well as political lobbying from state politicians, “This is a national disaster,” stated Congress leaders for Assam in the last year of flooding, “We want the Centre to build embankments and develop dredging projects with advanced early alert systems.”
How should adaptation in rivers look like, is there any consensus among experts in Adaptation: Adaptation experts largely agree that the current strategy for rivers – which relies primarily on hard engineering to prevent further damage since independence – isn’t enough; instead, it calls for a two-pronged approach in all rivers- combining hard infrastructure with nature-based solutions, as well as setting aside floodplain areas for nature and agricultural use only, in both the coastal and river river basin region of India. The national policy on disaster, while taking up both river-river and coastal bank erosion as national challenges, has, though been fragmented when it come to the implementation stage across the state country; so need to develop an adaptation model which covers all types of Indian rivers like the Ganga, Brahmaputra to the Sundarbans and other river system as riverine area which remains highly exposed to the current day climate changes, by taking proactive steps at national as well as state level.
